RODNEY E. NULL, 0F SAYBROOK, ILLINOIS.

GRAIN-CAR DOOR.

To all whom it may concern:

Be it known that I, RODNEY E. NULL, a citizen of the United States,residing at Saybrook, in the county of McLean, State of Illinois, haveinvented certain new and useful Improvements in Grain-Car Doors; and Ido hereby declare the following to be a full, clear, and exactdescription of the 1nvention, such as will enable others skilled in theart to which it appertains to make and use the same.

The invention relates to car doors and more particularly to the class ofdoors for grain cars.

The primary obj ect of the invention is the provision of a grain cardoor in which the same is formed of a plurality of sections adapted tobe opened outwardly of a car and are capable of being shifted verticallywhen in a closed position. l

Another object of the invention is the provision of a grain car doorwhich is simple in construction, durable in use, efficient in operationand inexpensive in the manufacture.

In the drawings accompanying and forming part of this specification isillustrated the preferred form of embodiment of the invention which, toenable those skilled in the art to practice the invention, will be setforth at length in the following description, while the novelty of theinvention will be included in the claims succeeding the description. Itis to be understood however, that changes, variations and modificationsmay be made such as come properly within the scope of the claimshereunto appended without departing from the spirit or sacriicing any ofthe advantages of the invention.

In the drawings: Figure 1 is a fragmentary side elevation of a car withthe grain car door shown in a. closed position. Fig. 2 is a verticalsectional view on the line 2 2 of Fig. 1. Fig. 3 is a horizontalsectional view on the line 3 3 of Fig. 1. Fig. 4 is a vertical sectionalview on the line 4 4 of Fig. 1 looking in the direction of the arrowwith the car door swung to the roof of the car, when not in use. Fig. 5is a side elevation of a portion of the car with the grain door swung inan open position.

Serial No. 474,072.

generally one side wall of a grain car, 9 the floor or bottom and 10 thetop or roof thereof and which car is of the usual or ordinaryconstruction, the same being provided with the usual door framedesignated generally by the numeral 11 with vertical posts 12 and inproximity to the latter are arranged vertical guide rods 13 which latterhave their upper ends pivotally connected as at 14 to depending bracketsor hangers 15 suitably secured at the top of the door frame so as topermit the said rods to be swung from a vertical to a horizontalposition and the said rods when in a vertical position have their lowerends engaged Vor locked by catch devices 16 to maintain the rods againstdisplacement wheny in this position.

` Connected to the guide rods 13 are grain doors each comprisingsections 17 and 18 which are connected together by hinges 19 to permitthe section 18 tobe swung outwardly when the occasion demands.Connecting the grain doors to the guide rods 13 are eye bolts 20 thesame secured to the sections 17 in any suitable manner and having theireyes encircling the said guide rods 13 so that the grain doors can bevertically shifted upon the said guide rods toward the roof of the car.

In the meeting edges of the sections 17 and 18 are suitably formedregistering sockets in which are mounted slidable locking bolts 21having a finger lug or piece 22 to permit the locking bolt-s to bemanipulated so as to be swung across the meeting edges of the sectionsto prevent the sectionV 18 from being swung outwardly with respect tothe section 17 of the door.

Secured to the sections 18 of the doors are handles 23 which latter arein the form of loop members and project outwardly from the outer facesof said sections so the same may be swung to an open position outwardlyof the car against the outside face of the side wall 8 thereof.

Suitably mounted in t-he sections 18 of the doors at their lower edgesare locking bolts 24: which latter are adapted to be moved intoengagement with suitable sockets formed in the flooring or bottom of thecar so as to lock the sections 18 against outward movement and tomaintain the doors in a closed position.

Suitably formed in the meeting edges of the sections 18 when in a closedposition are registering recesses accommodating sliding bolts 25 whichlatter are formed with finger lugs or pieces 26 to permit the same tolock the sections together against movement so as to prevent the bulgingof the sections 1S with respect to each other' due to the heavy weightof the grain against the car doors when in closed position. The meetingedges of the sections 17 and 1S are beveled as at 27 so as to form anoverlapped joint when the doors have been swung to closed position.

Depending from and pivoted to the roof 10 of the car are catches 28which latter are adapted to engage the free ends of the guide rods 18when swung from a vertical to a horizontal position so as to hold thegrain doors adjacent the roof of the car when not in use and after thecar has been emptied of its load.

In the sections 18 are suitably formed openings 29 which are locat-ed inthe lowermost portion of said sections and are adapted to be normallyclosed by slides 30 and upon shifting the said slides in one direction,grain will be permitted to flow through the openings 29 so as to relievepressure against the grain doors whereby the same can be shiftedvertically on the guide rods toward the roof of the car at the will ofthe operator.

That is claimed is-- 1. 1n a door for grain cars, the combination with acar body and a frame surrounding a door opening therein; of hangerssuspended from the top of the frame at each end thereof, guide rodspivotally suspend-ed at their upper ends from the hangers and movable inrecesses in the bottoni of the frame, said rods being limited fromoutward movement by the end walls of the recesses and adapted to beswung inwardly to a horizontal position transversely of the car upontheir pivots, inner and outer door sections hinged together upon theirouter faces, the outer door sections being pivota-lly and slidablyengaged with the guide rods and having their outer edges overlapping thesides of the door frame upon the inner side of the car, the inner doorsections being outwardly movable upon their hinges and the outersections being similarly movable upon the rods to place the outersections upon a common direction with the longitudinal extent of the carand the inner sections in a similar direction, sliding bolts mountedupon the bottom of the car frame to engage across the recesses inwardlyof the rods to hold the same at their outward limit, means engaging inthe coacting edges of the door sections to hold the same againstindependent movement and means carried by the inner edges of the innersections to engage the frame and prevent movement of the doorshorizontally upon the rods, said rods being capable of being supportedin a raised position inwardly of the car.

2. In a device of the class described, the combination with a car havinga door frame and guide rods pivotally connected at their upper ends ofthe frame adjacent each end of the doorway; of means for limiting theoutward movement of the rods in the bottom of the frame, means forholding the same in such position at their lower ends, doors carried byeach rod, eac-h door comprising two sections hinged upon their outersides for horizontal swinging movement relative to each other, eye boltsconnected with the outer sections and engaged with the rods to permithorizontal swinging and vertical sliding movement thereof upon the rods,sliding bolts coniined in coacting recesses in the abutting edges of thesections and provided with iinger pieces movable in slots in certain ofthe sections outwardly thereof to hold the same from movement relativeto each other and means for anchoring the inner sections to the frame.

In testimony whereof, I afliX my signature. in presence of twowitnesses.
